摘要:
Silicon nanohole arrays are disclosed as light absorbing structures for various devices such as solar photovoltaics. To obtain the same ultimate efficiency as a standard 300 micrometer crystalline silicon wafer, nanohole arrays require less silicon by mass. Moreover, calculations suggest that nanohole arrays may have efficiencies superior to nanorod arrays for practical thicknesses. With well-established fabrication techniques, nanohole arrays have great potential for efficient solar photovoltaics.
摘要:
The present invention provides an acrylic pressure sensitive adhesive composition having an element with a positive stress optical coefficient for a polarizing film and a polarizing film using the same.
摘要:
The present invention provides templating methods for replicating patterned metal films from a template substrate such as for use in plasmonic devices and metamaterials. Advantageously, the template substrate is reusable and can provide plural copies of the structure of the template substrate. Because high-quality substrates that are inherently smooth and flat are available, patterned metal films in accordance with the present invention can advantageously provide surfaces that replicate the surface characteristics of the template substrate both in the patterned regions and in the unpatterned regions.
摘要:
An optoelectronic device configured to operate at an electromagnetic radiation frequency having metal wire electrodes that are optically transparent as a result of the wires having an effective plasma frequency that is equal to or lower than the electromagnetic frequency at which the device operates. The effective plasma frequency of the wire is lowered by configuring the path of the wire between the terminal ends to be meandering, serpentine, U-shaped and in other non-linear configurations.
